Abstract
The invention discloses a driving front axle of an automobile, which relates to a driving mechanism of the automobile. The utility model is characterized in that the exterior casing and the axle housing of a deceleration assembly are steel plate integral structures after the steel plates are stamped and welded, the axle housing and an axle house flange of steel automobiles are integral, a steering knuckle is a structure connected by a U-shaped knuckle housing and a supporting seat pin, a U-shaped supporting seat of which the U-shaped port is outwards is fixed on the axle house flange, the U-shaped knuckle housing of which the U-shaped port is inwards is fixed on the stern tube of a wheel drum, the two U-shaped ports are opposite to each other and connected movably and fittedly and a universal joint is also a structure of double half shafts connected by the pin. The invention has the advantages that the invention can be elastic and transformed and is not easily broken when the invention is impacted by greater force as the axle housing and the supporting seat of the front axle are welded. The steering knuckle does not adopt a ball shape which is restricted by space but adopts a double U-shaped stand, of which the technique is simplified and the structural dimension can be enlarged. The enlargement of the structure can enable the dimension of the universal joint to be enlarged and the pin diameter between the two half shafts can be enlarged, so the invention can bear greater impact and does not break easily.
Description
Technical field:
The present invention relates to automobile drive mechanism, be specially adapted to car drive front axle.
Prior art:
The structure of car drive front axle is made up of universal-joint, drg, brake wheel, intermediate rod that the double-U-shaped double-pin in deceleration assembly, axle housing, axle housing flange, spherical steering swivel, the spherical steering swivel constitutes at present.The body skin of deceleration assembly, axle housing are that the disjunctor foundry goods is pegged graft, if this foundry goods protrusion on the bump road easily when the ground of road conditions difference, and the automobile front axle power maximum that is impacted, foundry goods can not elastic deformation, and fragility is big, the axle housing easy fracture.Spherical steering swivel is the joint of relative angle break-in between brake wheel and the axle housing, the little level of texture ratio brake wheel, and universal-joint is installed in the spherical crown inside of spherical steering swivel, therefore gimbal structure is restricted by the spherical crown internal diameter, spherical cap structure is less, and then two semiaxis space structures on the universal-joint also are limited, and two bearing pins that connect usefulness between two semiaxis are more restricted, pin diameter is little, then the little easy fracture of holding capacity.
Summary of the invention:
The objective of the invention is to overcome above-mentioned defective, a kind of car drive front axle is provided.
The solution of the present invention is: the body skin of deceleration assembly, axle housing are the steel plate conjoined structures that steel plate then is welded through punching press, the axle housing flange welding disjunctor of axle housing and steel car system forms, steering swivel is by U type joint shell and supporting base bearing pin connection structure, U type supporting base is fixed on the axle housing flange, U type mouth outwardly, U type joint shell is fixed on the wheel hub central siphon, U type mouth inwardly, two U type mouths connect using the bearing pin running-fit, and gimbal structure also is a Double half axle bearing pin connection structure.
The invention has the advantages that: forerunner's axle housing, supporting base are welded with steel plate, when being subjected to greater impact power, and can elastic deformation, not easy fracture.And steering swivel does not adopt the affined ball-type in space, adopts double-U-shaped, not only work simplification, and scantling of structure can amplify, and this size is amplified makes the gimbal structure size also scalable, and then the pin diameter between the two-semiaxle also can strengthen, can bear bigger impulsive force, not easy fracture.
Description of drawings:
Accompanying drawing 1 is structural representation of the present invention.
Accompanying drawing 2 is the axle housing structural representation.
Accompanying drawing 3 is the birds-eye view of Fig. 2.
The specific embodiment
Structure of the present invention is made up of universal-joint (6), drg (7), wheel hub central siphon (10), brake wheel (8), intermediate rod that the Double half axle double-pin in deceleration assembly (1), axle housing (2), axle housing flange (3), steering swivel, the steering swivel constitutes.
Body skin, the axle housing of deceleration assembly (1) is the steel plate conjoined structure that steel plate then is welded through punching press, axle housing (2) forms with axle housing flange (3) the welding disjunctor of steel car system, steering swivel is by U type joint shell (5) and supporting base (4) bearing pin connection structure, supporting base (4) is fixed on the axle housing flange (3), U type mouth outwardly, joint shell (5) is fixed on the wheel hub central siphon (10), U type mouth inwardly, two U type mouths connect using bearing pin, and universal-joint (6) structure also is a Double half axle bearing pin running-fit connection structure.
The steel plate conjoined structure is: axle housing (2) is welded for laterally zygomorphic half-bridge shell (2), half-bridge shell (2) structure is that two is the semicircle tubular shape, the curved semicircle tubulose in middle part, the aft end face at pipe shape middle part and spherical crown shape steel plate welding have constituted the body skin of deceleration assembly (1) behind two half-bridge shells (2) disjunctor, the rounded opening of its front end face is welded with annular flange on this circular open.This annular flange and deceleration assembly (1) bolt together, deceleration assembly (1) is installed in it.
Deceleration assembly (1) is connected with inner shaft by the transmission shaft that is installed in the axle housing (2), inner shaft is connected with outer semiaxis by universal-joint (6) again, the outer semiaxis other end then is connected with wheel hub central siphon (10), and deceleration assembly (1) realizes that by transmission shaft, inner shaft, bearing pin, outer semiaxis, wheel hub wheel hub drives successively.Drg (7) is installed in the brake wheel (8).
Turn to then is that to drive U type joint shell (5) by intermediate rod be that break-in is done to rotate in the center of circle with the bearing pin of running-fit between U type joint shell (5) and the U type supporting base (4).
Claims (2)
